ADJUSTABLE BED-REST.

Application filed August 25, 1920. Serial No. 405,847.

T 0 all 'w from it may concern Be it known that I, DAVID J. Coon, a citi- Zen of the United States7 residing at Tuscarora, in the .county of Elko and State of Nevada, have invented certain new and useful improvements in Adjustable Bed-Rests; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to bed rests adapted to be applied to bed frames and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide an attachment of the character stated which is of simple and durable structure and which may be easilyV and quickly manipulated whereby it may be pitched at a desired angle with relation to the bed frame and the mattress thereon in order that the head and upper portion of the body of the occupant of the bed maybe raised or lowered as desired.

With the above object in view the attachment comprises approximately U-shaped side bars adapted to be pivotally connected at one end with the side rails of a bed frame. Slats connect the intermediate portions of the said bars together and lie under the end portion of the mattress and between the mattress and the bed spring.

A shaft is journaled for rotation at the upper portion of the head board of the bed frame and drums are mounted upon the shaft. Means are provided for temporarily holding the shaft against rotation. Cables are arranged to wind upon the drums and the said cables are connected at their lower ends with springs which in turn are connected with the outer end of the bars. It is apparent that when the shaft is rotated the cables will be wound thereon or unwound therefrom and consequently the outer portion of the attachment is raised or lowered and carries With`it the mattress and hence means are provided for raising or lowering the head and body portion of the occupant of the bed.

In the accompanying drawings:

Figure 1 is a side elevation of a bed with the rest applied.

Fig. 2 is an end elevation of the same.

Fig. 3 is a side elevation of the rest detached.

Fig. 4 is a. top plan view of the same.

Fig. 5 is an enlarged transverse sectional view on the plane of line 5-5 of Fig. 2, looking in the direction indicated by the arrow.

Fig. 6 is a. detail sectional view on the plane of line 6 6 of F ig. 5.

The bed to which the rest is applied is of usual structure and includes a head board 1 and side rails 2. spring structure is mounted upon the side rails 2 in a usual manner and a mattress t is supported upon the spring 3.

The attachment comprises U-shaped bars 5 which are provided at one end with perforations 6 adapted to receive bolts 7 whereby they are pivotally secured to the side rails 2 at points between the ends thereof. The opposite end portions 8 of the side bars 5 are curved longitudinally and lie beyond the outer surface of the headboard 1. Yokes 9 are applied to the corner posts of the head board 1 and are provided with lugs 10 in which is journaled a shaft 1l. Drums 12 are xed to the sha-ft 11 in the vicinity of the end thereof and a hand wheel 13 is fixed to one end of the shaft 11. Collars 14 are mounted upon the intermediate portion of the shaft 1l and may be adjusted thereon and iXed so that they may lie adjacent the opposite sides of the lugs l0 whereby the shaft 11 is restrained against longitudinal movement through the lugs 10 but is free to rotate therein. A ratchet wheel 15 is fixed to the shaft 11 against one of the drums 12 and a pawl 16 is of the yokes 11 and adapted to engage in the spaces between the teeth of the ratchet wheel 15 whereby the shaft 11 is held against turning movement in one direction when the said pawl is in engagement with the teeth of the ratchet wheel.

Cables 17 are arranged to wind upon the drum 12 and the lower ends of the cables 17 are connected with springs 18 which in turn are connected with the lower ends of the portions 8 of the side bars 5. The intermediate portions of the side bars 5 are connected together by means of spaced cross slats 19. The slats 19 lie between the bed springs 3 and the mattress 4.

It is apparent that when the shaft 11 is rotated by using the hand wheel 13 the cables 17 are wound upon the drums 12 whereby the outer end portions of the bars 5 are.

raised and one end of the mattress 4 is pivotally mounted upon one.

pitched at an angle with relation to the other end thereof. Therefore means are provided for raising the hea-d and body of the occupant of the bed. Inasmuch as the cables 17 are connected with the outer ends of the bars 5 by springs 18 the head and body of the' occupant of the bed will be resiliently supported. After the cables have been Wound upon the drums, the pawls 16 may be engaged with the teeth ofI the ratchet wheel 15 whereby the partsy will be held at the adjusted position. Vhen it is desired to lower.` the end portion of the mattress which has been previously elevated the pawl 16 is disengaged from the teeth of the ratchet wheel 15 and the cables 17- are permitted to unwind from the drums 12.

Fromv the foregoing; description taken in conjunction with the accompanying drawings it will be seen that an adjustable bed rest of simple-and durable form is provided and that the same may be easily and quickly manipulated or adjusted to'V support the end portionofa mattress at adesiredfangle with relation -to the bodyj portion thereof.

Having thus describedV the invention, what I claim is:

1. A bed rest adaptedfto'be applied to a,

betweenfthe ends thereof, the other endsiof the bars beingdisposed beyond the end ofthe bed frame and being longitudinally curved, means connecting the intermediate portions of said bars, means for raising the second mentioned ends of said bars, supporting and operating means for the last mentioned means, and resilient connections between said raising means and the second mentioned means of saidbars.

2. A bed rest adapted to be applied to a bed frame comprising U-shaped bars, means pivotally connectino' one end of the bars with the side rails ot the bed frame at points between the ends thereof,vthe other end of the bars being disposed beyond the end of the bed frame and being longitudinally curved, cross slats connecting the intermediate portions of the bars together', yolres adapted'to be applied to the upper portion of the headboard of the bed frame, a shaft journaled in the yoke. means for restraining the shaft' against longitudinal movement in the yoke, drums mounted upon the shaft, means for turning the shaft, means for holding the shaft against turning movement.y cables arranged to wind .upon the drum, and springsconnected with the cables and connected at'their lower ends with the outei` ends of'thebars.

In ytestimony whereof I affix my signature in presence of two witnesses.
